A steel grab is a device used to grab, move and stack steel. In the process of use, there are often some failures. This article will introduce the common faults and solutions of the steel grab machine.

Fault 1: The steel grab machine can not start

Possible causes:

1. If the power supply is faulty, check whether the power cable is securely connected and whether the power supply is normal.

2. Switch fault: Check whether the main control switch is on. If yes, check whether the switch cable is loose or damaged.

3. Motor failure: Check whether the motor is running normally, if the motor is damaged, the motor needs to be replaced.

Solution:

1. Check whether the power cable is secured to ensure that the power supply is normal.

2. Check the status of the main control switch. If the switch is loose or damaged, repair or replace it in time.

3. Check the operation of the motor. If it is damaged, replace the motor.

Fault two: The grasp of the steel machine is insufficient

Possible causes:

1. Insufficient oil pressure: Check whether the hydraulic oil in the hydraulic system is enough, if insufficient, add hydraulic oil.

2. Valve damage: Check whether the valve in the hydraulic system is damaged, if there is a damaged valve need to be repaired and replaced.

3. Oil pump failure: Check whether the hydraulic pump is working normally, if there is a problem, replace the pump.

Solution:

1. Add enough hydraulic oil to ensure the tightness of hydraulic oil.

2. Check the valves in the hydraulic system. If there are damaged valves, they need to be repaired and replaced.

3. Check the hydraulic pump, if there is a fault, need to replace the pump.

Fault 3: Shaking occurs when grabbing the steel machine

Possible causes:

1. The structure of the equipment is unstable: check whether the overall structure of the steel grab machine is stable, if there is a problem, it needs to be adjusted and strengthened.

2. Gripper failure: Check whether the gripper is damaged or loose, and if there is a problem, it needs to be repaired.

3. Motor failure: Check whether the motor is running normally, if there is a problem, replace the motor.

Solution:

1. Check the overall structure of the steel grab machine to ensure the stability of the structure. If there is any problem, it needs to be strengthened and adjusted.

2. Check whether the claw is damaged or loose, and repair it if there is a problem.

3. Check the motor operation, if there is a fault need to replace the motor.

Fault four: The grasping machine can not accurately grasp the steel

Possible causes:

1. Control system failure: check whether the connection lines and sensors in the control system work normally, if there is a problem, it needs to be repaired.

2. Hydraulic system failure: Check whether the valve and sensor in the hydraulic system are working normally, if there is a problem, it needs to be repaired.

3. Sensor failure: Check whether the sensor is damaged or loose, and repair or replace it if necessary.

Solution:

1. Check the connection lines and sensors of the control system to ensure normal operation. If there is any problem, it should be repaired in time.

2. Check the valves and sensors in the hydraulic system to ensure normal operation. If there are problems, repair them in time.

3. Check whether the sensor is damaged or loose. If there is any problem, repair or replace it in time.

In SUMMARY:

Grasp in the process of use often encounter some failures, the usual solution includes checking the state of the power supply, switch and motor, adding hydraulic oil, replacing the pump and repairing the valve, adjusting the structure and reinforcement of the grasp, repairing and replacing the grasp, sensors and so on. For some faults of uncertain causes, professional and technical personnel need to be checked and repaired. When maintaining the steel grab machine, you can regularly replace and add hydraulic oil, check the status of the power line and connector, and regularly clean and lubricated the equipment. These maintenance measures can reduce the probability of failure and extend the service life of the grasping machine.
